Specification of Letters Patent.

Patented June 4, 1907.

Application filed July 23, 1906. Serial No. 327,410.

To all whom it ntcey concern:

Be it known that I, BIRGER LJUNGsTRoM, a subject of the King of Sweden, and residing at Fleminggaten, Stockholm, Sweden, engineer, have invented certain new and useful Improvements in Centrifugal Machines for Drying and other Purposes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in'the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The resent invention relates to improvements in centrifugal machines for washing, drying or dyeing purposes and has for its object to provide or dyeing the goods by means of air, liquid, steam or the like, such for instance, for washing, and drying sugar crystals which have been separated from the molasses in the same machine while the machine is running and the goods are exposed to centrifugal force.

The invention is shown on the annexed drawing in which Figure 1 shows the invention in axial sec tion applied to a machine with conical plates. Fig. 2 1s a machine partly in cross section with vertical, curved plates In the figures a designates plates, which are conical in Fig. 1 and vertical and curved in Fig. 2. These plates are provided with outlets, perforations in the plates being shown. Enveloping each of said plates a is a guiding plate I), which is solid. The object of these guiding plates 1) is to catch the liquid and lead the hquid to the periphery, from where it is thrown out into a receiving vessel, which is not shown on the drawing. The goods or mass, which is to be separated anddried is brought into the machine in the spaces 0 between the plates on and b. Enveloped by each separating plate a is a secondary plate d, which may be solid as in Fig. 1 and then of less diameter than the other plates or it may be perforated as in Fig. 2. 1n the spaces 6 between the secondary lates d and the guiding plates 1) the steam, rying air or the like is brought into the machine. In Fig. 1 the steam, drying air or the like does not reach the mass before the separating means for washing, drying it has passed nearly to the edges of the separating plates (1; in Fig. 2 on the contrary, it passes through the perforations in the secondary plates (1. The drying material follows the same course as the liquid, 'L. e. it passes through the outlets in the separating plates a and follows the guiding plates b to the periphery. 1

Instead of washing or drying the mass, it may be dyed with the described apparatus.

Having now fully described my invention, what I claim and desire to protect by Letters Patent is:

1. In a centrifugal machine of the character and for the purpose described, in combination, a series of separating plates, said separating plates being provided with outlets, a

its corresponding separating plate, and means whereby the drying, dyeing or washing material, admitted on the side of each of said secondary plates remote from the corresponding se arating plates, may be led to the opposite si through the mass when it is under the action of centrifugal force.

2. In a centrifugal machine of the character and for the purpose described, in combi nation, a series of separating plates, said separating plates being provided with outlets, perforated secondary plates, each of said separating plates enveloping a corresponding secondary plate, whereby drying, dyeing or washing material admitted to the side of the secondary plate remote from the corresponding separating plate, may be led to the opposite side of the secondary plate and through the mass when it is under the action of centrifugal force.

3. In a centrifugal machine of the character and for the purpose described, in combination, a series of separating plates, said separating plates being provided with outlets, a series of secondary plates, each of which is enveloped by its corresponding separating plate, there being a passage from one side to the other side of said secondary plates whereby the drying, dyeing or washing material admitted on the side of said secondary plate remote from the corresponding separating plate, may be led to the opposite side of the secondary plate and through the mass when it is under the action of centrifugal force, and

series of secondary plates, each enveloped by e of the secondary plate and a solid guiding rating plate, to the periphery.

4. In a centrifugal machine of the charac ter and for the purpose described, in combination, a series of separating plates, said plates being provided with outlets, perforated secondary plates, each of which is enveloped by its corresponding separating plate, whereby drying, dyeing or washing material admitted to the side of the secondary plate remote from the corresponding separating plate, may be led to the opposite side of the secondary plate and through the mass when it is under the action of centrifugal force, and a solid guiding plate, enveloping each of the separating plates to catch and guide the liquid to the periphery.

5. In a centrifugal machine of the character and for the purpose described, in combination, a separating plate, said plate being provided with outlets, a secondary plate enveloped by the separating plate and means whereby the drying, dyeing or washing material, admitted on the side of said secondary plate remote from the separating plate, may be led to the opposite side of the secondary plate and through the mass when it is under the action of centrifugal force.

6. In a centrifugal machine of the character and for the purpose described, in combination, a separating plate, said separating plate being provided with outlets, a perforated secondary plate enveloped by said separating plate whereby drying, dyeing or plate enveloping each sepacatch and guide the liquid to washing material admitted to the side of the secondary plate remote from the separating plate, may be led to the opposite side of the it is under the action of pentrifugal force.

7. In a centrifugal machine of the character and for the purpose described, in combination, a separating plate, said separating plate being provided with outlets, a secondary plate enveloped by said separating plate there being a passage from one side to the other side of said secondary plate whereby the drying, dyeing or washing material admitted to the side of said secondary plate remote from the separating plate, may be led to the opposite side of the secondary plate and through the mass when it is under the action of centrifugal force, and a solid guiding plate enveloping said separating plate to catch and guide the liquid to the periphery.

8. In a centrifugal machine of the character and for the purpose described, in combination, a separating plate provided with outlets, a perforated secondary plate enveloped by said separating plate whereby drying, dyeing or washing material admitted to the side of the secondary plate remote from the separating plate, may be led to the opposite side of the secondary plate and through the mass when it is under the action of centrifugal force and a solid guiding plate enveloping said separating plate to catch and guide the liquid to the periphery.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
